Stellar Sleep: Insomnia CBT is a lifestyle app developed by Merlin Collective LLC for iPhone. This free app aims to help users improve their sleep quality using a science-backed approach. With just 5 to 10 minutes a day, users can benefit from a clinically-tested curriculum designed to address various aspects of sleep improvement.

The app's curriculum is based on research by top sleep psychologists, therapists, and researchers. It covers a wide range of topics, including stimulus control, cognitive restructuring, sleep restriction therapy, building strong sleep habits, calming down a racing mind, relaxation techniques, and more. With over 100 science-backed modules, the app provides personalized recommendations based on the user's specific sleep needs.

In addition to the core sleep curriculum, Stellar Sleep also offers a comprehensive library of nature sounds, breathing exercises, progressive muscle relaxation exercises, bedtime stories, sleep music, and guided meditations to help users relax and release anxiety. Users can even integrate sleep data from their wearables through Apple Health.

Please note that in the United States, Stellar Sleep has not been cleared by the FDA for use in the diagnosis or treatment of a disease or condition, such as Insomnia Disorder.
